Investors interested in a long running portfolio need look no further than the Schrodinger Portfolio. This is truly a passively run portfolio as there has been almost no trading over the last ten years of operation. We do rebalance when necessary.
The current allocation plan is oversubscribed in bonds and treasuries. There are no plans to sell down bonds so long as the market continues to oscillate wildly.
The following screen shot shows the performance of the Schrodinger over these many years. The asset allocation is essentially unchanged, although we did add international REITs in the last few years. There are no plans to add international bonds.
